No. 09/419,571, filed on Oct. 18, 1999, which claims benefit of U.S. Provisional Patent Application No. 60/106,094, filed Oct. 29, 1998, both of which are incorporated herein in their entirety.

FIELD OF THE INVENTION

This invention relates to gel compositions which include esters, ethers, alcohols, naturally-occurring fats and oils, or mixtures thereof.

BACKGROUND OF THE INVENTION

Numerous gel compositions are known in the art. Some have proven to be a convenient and efficient vehicle or carrier for the application of various active ingredients to the skin. Such active ingredients include antiperspirants, deodorants, perfumes, sunscreens, cosmetics, emollients, insect repellants, medicaments, and the like. Products incorporating a gel composition and those made entirely from a gel composition may be in the form of a soft gel or a stick. Rubbing a soft gel or solid stick containing an effective amount of an active ingredient dissolved or dispersed therein against the skin causes transfer of the gel composition to the skin surface in a layer form, leaving the active ingredient within the layer on the desired skin surface.

For topical administration of various cosmetic and health and beauty materials to the skin, a gel composition preferably should have one or more of the following desired properties: transparency, compatibility with the active ingredient, controlled release of the active ingredient, minimization of skin irritation, and the ability to suspend organic and inorganic materials, such as color pigments, glitters, water, air, metal oxides, sunscreen active particulates, and fragrances. In sunscreen applications, it is desirable if the gel itself could act as a sunscreen active ingredient. Moreover, it should moisturize the skin and exhibit water wash-off resistance, but should not have significant syneresis. For industrial applications, a gel base may offer one or more of the following properties: suspension, moisture barrier, rheology, solvency, controlled release, wetting, self-emulsifying, etc. For example, in the paint industry the properties that are important are suspension and controlled release.

A gel composition typically is made by mixing one or more compounds to be gelled with a gelling agent. Known gelling agents include metal soaps, surfactants, homopolymers, ionic homopolymers and copolymers, fumed silica, natural derivatives of gums, waxes, clay, and so on. Common gelling agents for cosmetic oils are fatty acid soaps of lithium, calcium, sodium, aluminum, zinc, and barium. A number of homopolymers and copolymers, such as atatic ethylene-propylene copolymers, have been used to gel hydrocarbons. For example, gelled mineral oils have been available; however, gel compositions including an ester, ether, alcohol, or vegetable oil are less common. Because gel compositions including an ester, alcohol, ether, or naturally-occurring fat or oil may provide a better alternative to hydrocarbon gels, there is a need for exploring methods of making such gel compositions.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the invention are, in part, based on the discovery that esters, alcohols, ethers, and naturally-occurring fats and oils can be gelled by using selected polymeric gelling agents. For example, diblock copolymers, triblock copolymers, radial polymers, star polymers, multi-block copolymers, butyl rubbers, alkyl galactomannan, and mixtures thereof can be used as gelling agents to obtain gelled esters, gelled ethers, gelled alcohols, and gelled naturally-occurring fats and oils. In some embodiments, the gel compositions and products made therefrom are transparent or substantially transparent. In other embodiments, the gel compositions and products made therefrom are semi-transparent, hazy, or opaque. These gel compositions and products made therefrom each have numerous cosmetic and industrial applications.

A gel refers to a two-phase colloidal system comprising a liquid and a solid in the form of thickened liquid, semi-solid or solid. A gel also can refer to a composition that is either physically cross-linked by virtue of entangled polymer chains, or chemically cross-linked by virtue of covalent bonds such that it swells, but does not dissolve, in the presence of liquid. A gel typically is obtained by use of a gelling agent. The term “polymer” used herein includes both homopolymer and copolymer. A homopolymer is a polymer obtained by polymerizing one type of monomer, whereas a copolymer is a polymer obtained by polymerizing two or more types of monomers. “Block copolymer” refers to a copolymer in which like monomer units occur in relatively long, alternate sequences on a chain.

The term “opaque” refers to the optical state of a medium whose molecular aggregation is such that light cannot pass through. Therefore, light transmission through an opaque medium is substantially close to zero. On the other hand, the term “transparent” refers to the optical state of a medium through which light can pass through so that an object can be seen through it. As defined, the term “transparent” includes any optical state which is not opaque. A medium is considered transparent even if only a small fraction of light passes through it. Thus, a clear gel and a translucent gel are considered transparent.

In some embodiments of the invention, a block copolymer capable of forming a three-dimensional network through physical cross-linking is used as the gelling agent. Suitable block copolymers include at least one rigid block and one elastomeric block. The rigid blocks of a block copolymer form rigid domains through which physical cross-linking may occur. The physical cross-linking via these rigid domains yields a continuous three-dimensional network. In the presence of heat, shear, or solvent, the rigid domains soften and permit flow. Upon cooling, removal of shear, or solvent evaporation, the rigid domains reform and harden, locking the elastomeric network in place. Preferably, suitable block copolymers include diblock copolymers, triblock copolymers, radial polymers, star polymers, multi-block copolymers, and mixtures thereof.

The amount of a gelling agent may range from about 0.2% to about 80% by weight, depending on the desired properties of the resulting gel. Preferably, a gelling agent is present in the gel from about 1% to about 40% by weight. More preferably, a gelling agent is present in the gel about 5% to about 20% by weight. In embodiments where both a diblock copolymer and a triblock copolymer are used, the triblock copolymer may range from about 0.1% to about 10%, and the diblock copolymer from about 1% to about 40%.

FIG. 1 illustrates the typical chain structure of a diblock copolymer. The polymer chain of the diblock copolymer includes two blocks: a rigid block and an elastomeric block. The rigid block is represented by diamonds. The elastomeric block is represented by circles. The rigid block typically is composed of polystyrene, polyethylene, polyvinylchloride, phenolics, and the like; the elastomeric block may be composed of, ethylene/butadiene copolymers, polyisoprene, polybutadiene, ethylene/propylene copolymers, ethylene-propylene/diene copolymers, and the like. As such, suitable diblock copolymers include, but are not limited to, styrene-ethylene/propylene copolymers, styrene-ethylene/butadiene copolymers, styrene-isoprene copolymers, styrene-butadiene copolymers.

FIG. 2 illustrates the chain structure of a triblock copolymer. As illustrated in FIG. 2, each polymer chain includes two rigid blocks at either end and a middle block which is elastomeric. This is a preferred triblock copolymer structure, although a triblock copolymer with two elastomeric end blocks and a rigid middle block also can be used. Suitable triblock copolymers include, but are not limited to, styrene-ethylene/propylene-styrene copolymers, styrene-ethylene/butadiene-styrene copolymers, styrene-isoprene-styrene copolymers, and styrene-butadiene-styrene copolymers. Multi-block copolymers are similar to diblock copolymers or triblock copolymers, except that the multiple block copolymers include additional elastomeric blocks and/or rigid blocks as illustrated in FIGS. 5A-5B.

In addition to the linear chain structure, branched homopolymers or copolymers also may be used. FIGS. 3-4 illustrate the chain structure of a radial polymer and a star polymer. It should be noted that one or more functional groups may be grafted onto the chain of any of the aforementioned polymers. In other words, any of the above polymers may be modified by grafting. Suitable functional groups for grafting depend on the desired properties. For example, one or more ester groups, silane groups, silicon-containing groups, maleic anhydride groups, acrylamide groups, and acid groups may be grafted. In addition to grafting, the above polymers may be hydrogenated to reduce unsaturation before they are used as gelling agents.

Numerous commercially available block copolymers may be used in embodiments of the invention. For example, various grades of copolymers sold under the trade name of Kraton® from Shell Chemical Company can be used as a gelling agent. In addition, copolymers sold under the trade name of Vector® available from Dexco® and Septon® from Kuraray also may be used. U.S. Pat. No. 5,221,534, U.S. Pat. No. 5,578,089, and U.S. Pat. No. 5,879,694 disclose block copolymers which may be used in embodiments of the invention, the disclosures of the three patents are incorporated by reference in their entirety herein. Table 1 lists some commercially available block copolymers which may be used in embodiments of the invention. It is noted that additional suitable block copolymers may include, but are not limited to, polystyrene/polyester, polyether/polyamide, polyether/polyester, polyester/polyamide, polyether/polyurethane, polyester/polyurethane, poly(ethylene oxide)/poly(propylene oxide), nylon/rubber, and polysiloxane/polycarbonate.

It should be noted that block copolymers are not the only gelling agents that can be used in embodiments of the invention. Other types of polymers also may be used. Homopolymers which are capable of effecting strong molecular interaction between polymeric chains can be used as gelling agents. One such example is butyl rubber, which can thicken oil due to its compatibility with oil and high molecular weight. Specifically, a polybutadiene polymer sold under the trademark of Solprene®. S200, which is available from GIRSA Industrias Negromex, S. A. de C. V. (INSA), can be used as a gelling agent. Other homopolymers capable of forming hydrogen bonding may include polyamide, polyester, and polyolefin. Still another example is alkyl galactomannan, which is capable of forming strong hydrogen bonding. Alkyl galactomannan is available from Hercules Incorporated under the trade name of N-HANCE® AG50 and AG200. Alkyl galactomannan is a polymer obtained by modifying natural products. It is especially effective in gelling esters and naturally-occurring fats and oils.

In accordance with embodiments of the invention, a gelled ester composition is obtained by gelling an ester compound with a triblock copolymer, a star polymer, a radial polymer, a multi-block copolymer, or mixtures thereof. Optionally, the gelled ester composition may further include one or more diblock copolymers. When a diblock copolymer is used along with one of triblock copolymers, star polymers, radial polymers, and multi-block copolymers, the resulting gel composition is substantially free of mineral oils. Suitable esters also may be gelled by alkyl galactomannan, polybutadiene, or other aforementioned polymers.

Any ester compound may be used in embodiments of the invention to obtain a gelled ester composition. An ester is defined as a compound that includes one or more carboxylate groups: R—COO—, where R is hydrogen, hydrocarbyl, phenyl, methoxyphenyl, alkylphenyl, substituted alkyl, substituted phenyl, or other organic radicals. Suitable esters include monoesters, diesters, triesters, etc. For example, one class of suitable esters that can be gelled is represented by the following formulas:

where n=1, 2, 3, and 4, and R₁ includes hydrogen, hydrocarbyl, phenyl, methoxyphenyl, alkylphenyl, substituted alkyl, and substituted phenyl; and R₂ includes hydrogen, hydrocarbyl, phenyl, methoxyphenyl, alkylphenyl, substituted alkyl, substituted phenyl, alkylene, phenylene, substituted alkylene, substituted phenylene, etc. It is noted that a suitable group for R₂ depends on whether n is 1, 2, 3, or 4.

Another class of suitable esters that may be gelled in embodiments of the invention is represented by the following formula:

where R₃ includes alkylene, phenylene, substituted alkylene, and substituted phenylene.

Still another class of suitable esters that may be gelled in embodiments of the invention is represented by the following formula:

where R₄, R₅, and R₆ individually include alkylene, phenylene, substituted alkylene, and substituted phenylene; R₇, R₈, and R₉ individually include hydrogen, hydrocarbyl, phenyl, methoxyphenyl, alkylphenyl, substituted alkyl, and substituted phenyl.

Preferred esters and their chemical formulas are listed in Table 2.

The gel compositions in accordance with embodiments of the invention may be obtained by the following method. First, one or more compounds to be gelled are mixed with a gelling agent. Second, the mixture typically is heated to a temperature in the range of about 70.degree. C. to about 140.degree. C., although other temperatures also are acceptable. The mixture is agitated until a homogeneous mixture is obtained. The homogeneous mixture is then cooled to room temperature. A gel composition is thus obtained. It is noted that the compound to be gelled need not be mixed with a gelling agent before heating. Instead, the compound may be heated to a desired temperature first, and then the gelling agent is added to the compound.

The following examples are given to illustrate embodiments of the invention. They are merely exemplary and are not intended to limit the scope of the invention otherwise described herein. All numerical values disclosed herein are approximate numbers. In some examples, an antioxidant was added in an amount of about 0.02%. Any antioxidants can be used. One suitable antioxidant is 2,6-di-tert-butyl-4-methylphenol (“BHT”).

Example 8

An in-vivo test was conducted to evaluate the waterproof efficacy of a sunscreen lotion based on a gelled ester composition. The in-vivo test procedure was conducted in accordance with the FDA monographs for sunscreen testing published in Federal Register, Vol. 43, No. 166, Aug. 25, 1978. Briefly, a finished sunscreen lotion was applied to a skin surface which was subsequently submerged in water. Before water immersion, the sun protection factor (“SPF”) was measured. After eighty minutes of water immersion, the SPF value was measured again. The percentage of the remaining SPF is indicative of the waterproof efficacy of the sunscreen lotion.

In this example, two sunscreen lotions were prepared according to Table 7. Both lotions contained approximately the same amount of a sunscreen active ingredient, i.e., octyl methoxycinnamate (“OMC”). Sunscreen Lotion A included gelled OMC, whereas Sunscreen Lotion B included neat OMC. Both sunscreen lotions contained approximately the same amounts of other ingredients as indicated in Table 7.

TABLE 7 Sunscreen Sunscreen Ingredient Lotion A Lotion B De-ionized water 45.74 45.74 Tetra sodium EDTA 0.10 0.10 Proplyene Glycol 2.50 2.50 Carbopol 940 (2% solution) 25.00 25.00 DEA-cetyl phosphate 1.00 1.00 Cetearyl Alcohol and Ceteareth 20 1.50 1.50 Mineral oil — 1.26 Octyl Methoxycinnamate — 7.50 Octyl Methoxycinnamate + Hydrogenated 8.76 — Ethylene/propylene/styrene copolymers + Hydrogenated Butylene/ethylene/styrene copolymers Dimethicone 2.00 2.00 Diisodecyl Adipate 7.00 7.00 C₁₂₋₁₅ Alkyl Benzoate 5.00 5.00 Triethanol amine 0.40 0.40 Diazolidinyl urea + propylene glycol + 1.00 1.00 methylparaben + propylparaben Remaining SPF after 80 min. water immersion 84% 69%

After eighty minutes of water immersion, the remaining SPF for Sunscreen Lotion A was about 84% of the pre-immersion SPF. As to Sunscreen Lotion B, the remaining SPF was about 69% of its pre-immersion SPF. Therefore, the test result indicates that inclusion of a gelled sunscreen active ingredient increases the waterproof efficacy of the sunscreen lotion.

Example 9

This example shows that gelled esters are comparable to petrolatum as an occlusive agent. An in-vivo skin barrier test was utilized to evaluate a gelled ester's ability to enhance the barrier function of the stratum corneum of human skin. Three different ester gels were formulated and evaluated in this test. Their respective formulations are listed in Table 8.

An independent laboratory conducted Trans-Epidermal Water Loss (“TEWL”) testing using the above gel compositions. Thirteen subjects were employed. TEWL measurements were taken on each subject at baseline and at 1, 2, and 3 hours after the application of a test material. A Servomed® Evaporimeter was used to measure the effectiveness of a topically applied test material. The evaporimeter samples relative humidity at two points above the skin surface which allowed the rate of water loss to be calculated from the measured humidity gradient. Petrolatum also was included in the measurements. The data obtained from the TEWL measurements are presented in Table

TABLE 9 Test Hour 1 Hour 2 Hour 3 Material Baseline mean Δ % mean Δ % mean Δ % Gel No. 1 7.07 5.47 22.6% 5.44 23.1% 5.26 25.6% Gel No. 2 6.66 5.37 19.4% 5.14 22.8% 4.72 29.1% Gel No. 3 6.76 5.79 14.3% 5.49 18.8% 5.25 22.3% Petrolatum 6.64 4.64 30.1% 4.28 35.5% 4.13 37.8% Note Δ % = (Baseline − Mean) * 100/Baseline

The data indicate that all three gelled esters are effective in retaining moisture in the skin. Consequently, gelled esters can be used as an occlusive agent in various health and beauty aid compositions.

Example 10

This example shows that a gelled composition has significantly higher loading capacity as a suspension system. To compare the loading capacity of gelled soybean oil with that of neat soybean oil, two experiments were conducted: about 3 grams coated TiO.₂ powder were suspended in about 97 grams of neat soybean oil; and about 50 grams of the same coated TiO.₂ powder were suspended in 50 grams of gelled soybean oil. No dispersant agent was used in either suspension system. The gelled soybean oil was made from the following formulation: about 85.9 wt. % of commercially available soybean oil and about 14 wt. % of Kraton® D1102. It was observed that only about 2 wt. % of TiO.₂ remained suspended in the neat soybean oil. In contrast, about 50 wt. % of TiO.₂ was suspended in the gelled soybean oil. It is surprising that the loading capacity of gelled soybean oil is about 25 times more than that of neat soybean oil. The increased loading capacity by using a gelled naturally-occurring fat or oil should result in improved performance and cost savings.

Accordingly, the gel compositions in accordance with embodiments of the invention have numerous cosmetic and industrial applications. The gel compositions may be used alone or in combination with one or more additional ingredients. For example, the gel compositions are suitable as lubricants, suspending agents, emulsion stabilizers, thickening agents, personal care ingredients, air freshener components, pesticide and insecticide components, ingredients for candle and ornamental products, pharmaceutical carriers and carrier ingredients, ointment base ingredients, sporting goods, and vehicles for carrying other materials. Since esters are generally considered as biodegradable materials, this allows gelled esters to find application in products where minimal pollution is desired. Examples include fishing line lubricant, solder flux, agricultural dust reduction and lubrication, textile coating, protective coating for transporting fragile or environmentally-sensitive materials, and biodegradable oils and greases.

It has been discovered that the gel compositions in accordance with embodiments of the invention keep solids and/or liquids substantially uniformly suspended and evenly dispersed over a substantial period of time. The suspended liquids and/or solids may be present in the gel in amounts of up to about 95 weight percent. Suitable solids and/or liquids that can be suspended in the gel include any solid or non-hydrocarbon oil liquid which will disperse into the gel and remain substantially suspended or evenly dispersed therein.

Examples of suitable solids include, but are not limited to, zinc oxide, coated zinc oxide, surface-treated zinc oxide, titanium dioxide, coated titanium dioxide, surface-treated titanium dioxide, phosphorescent substances, fluorescent materials, molybdenum oxide, zinc sulfide, copper-dopped zinc sulfide, graphite, explosive materials, pesticides, herbicides, fungicides, insecticides, plasticizers, air sensitive chemicals, moisture sensitive chemicals, boron nitride, iron oxides, talc, mica, plastics, polymers, silica, silicon dioxide, aluminum oxide, inorganic materials, organometallic materials, metal particles, medical materials (such as antibacterials, antibiotics, antimicrobials, antifungals, and anesthetics), glass, clays, gums, capsules containing an active ingredient, starch, modified starch, other encapsulated materials, and mixtures thereof.

Examples of oil insoluble liquids which can be suspended in the gels include, but are not limited to, water, water containing one or more water soluble materials, glycerin, propylene glycol, butylene glycol, alcohols, acids, surfactants, emulsifiers, polyglycerols, ethers, polar esters, fluorinated compounds, perfluoropolyethers, silicones, silicon-containing compounds, and the mixtures thereof.

Pending U.S. patent application Ser. No. 09/007,838, entitled “Hydrocarbon Gels as Suspending and the Dispersing Agents and Products,” filed Jan. 15, 1998, discloses methods of making a suspension system based on gelled hydrocarbons. The disclosed methods can be utilized in embodiments of the invention to make suspension systems which are based on gelled esters, gelled alcohols, gelled naturally-occurring fats and oils, or gelled ethers. The disclosure of the above-referenced patent application is incorporated by reference in its entirety herein.

The gel compositions in accordance with embodiments of the invention also have a wide spectrum of cosmetic applications when the gel compositions include an effective amount of one or more cosmetic and health and beauty aid ingredients. By “effective amount,” it is meant that a sufficient amount of the ingredient is present to be effective for the indicated purpose in the composition. An effective amount may range from about 0.001 to about 80 wt. %. By “cosmetic and health and beauty aid ingredients,” it is meant any material which can be applied topically to the human skin or any part thereof for cleansing, beautifying, promoting attractiveness, and protecting or altering the appearance of the skin without altering or interfering with the physiological competence of the human skin or body. Included within this definition are creams, lotions, emollients, fragrance oils, moisturizers, humectants, cosmetic oils, and so on. The gel compositions in accordance with embodiments of the invention also may contain skin care preservatives, diluents, surfactants, anti-wrinkle agents, and the like.

Furthermore, the gel compositions may be utilized to manufacture various over-the-counter (“OTC”) products. An OTC product may be made entirely from a gel composition; or only a component of the OTC is made from the gel composition. Examples of OTC products include, but are not limited to, antiperspirants, lip balms, and sunscreen (e.g., natural sunblocks, such as submicron particles of metal oxides or synthetic sunblock agents, such as octyl methoxycinnamate and benzophenone-3).

As mentioned above, the gel composition in accordance with embodiments of the invention may be utilized as carrier vehicles for topical administration of various cosmetic and health and beauty aid materials to the skin. Thus, such materials can be incorporated into the gel which are applied to the skin to be absorbed, to form a film on the skin, to provide a cooling sensation, to treat dry skin or oily skin, to work a material into the skin, to alter the overall texture of the skin, or to change color. All of these effects are sought to be achieved by various health and beauty aid products. Methods for making such skin care products are known in the art. For example, U.S. Pat. No. 5,558,872 discloses a clear gelled mineral oil based skin protectant. Similar skin protectants may be made by substituting the mineral oil gel by the gel compositions in accordance with embodiments of the invention. The disclosure of U.S. Pat. No. 5,558,872 is incorporated by reference in its entirety herein.

It is noted that preferred uses of the gel compositions in accordance with embodiments of the invention include formation of thickened liquids, soft gels and semi-solid gels. Gels are particularly useful in waterproofing sunscreen compositions, makeup, mascara, etc. They also are useful in petrolatum-based products, such as petroleum jelly, makeup foundation, and night creams. They also can be used as substitutes for water-soluble polymers in products, such as lip rouge-cream, eyeliner liquid, and the like. They also may be used as a gelling agent in facial oil.

Semi-solid or solid gels have applications as toiletry sticks, such as a stick insect repellant or a matrix for clear or opaque stick products, which include deodorants, antiperspirants, lipsticks, analgesics, blushers, solid lotions and solid absorbable flexible gels. Methods for making such cosmetic sticks are known. For example, U.S. Pat. No. 5,756,082 discloses a cosmetic stick composition based on a hydrocarbon oil gel. The disclosed hydrocarbon oil gels may be substituted by the gel compositions in accordance with embodiments of the invention to make cosmetic stick compositions. The disclosure of U.S. Pat. No. 5,756,082 is incorporated by reference in its entirety herein.

As demonstrated above, the gel compositions in accordance with embodiments of the invention have a wide range of industrial and cosmetic applications. When so used, the gel compositions may exhibit one or more of the following properties or advantages: transparency; compatibility with active ingredients; reduction or elimination of syneresis; ability to act as a vehicle to provide a stable suspension of an ingredient; moisturization; enhancement of wash-off resistance; provision of improved SPF when formulated into sunscreen products; reduction in absorption and irritation; elimination or minimization of whitening effect; ability to act as a cosmetic base; controlled release of volatile ingredients; and formulation with less emulsifiers. Other properties and advantages are apparent to a person of ordinary skill in the art.

While the invention has been described with respect to a limited number of embodiments, modifications and variations therefrom exist. For example, although suitable esters, ethers, alcohols, and naturally-occurring fats and oils have been described with some depth, other compounds also can be used. Additional suitable esters may include alkoxylated fatty acids, glyceryl ethers, and sorbitan derivatives. Additional suitable alcohols may include alkanolamides, alkanolamines, fatty alcohols, polyols, phenols, and sterols. Additional suitable ethers include heterocyclic ethers, e.g., tocopherol, alkoxylated alcohols, alkoxylated amides, alkoxylated amines, alkoxylated carboxylic acids, polymeric ethers, and glyceryl ethers. Similarly, naturally-occurring fats and oils may include so-called “essential oils,” which are volatile organic constituents of plants normally obtained by distillation. In addition to the above-described compounds, aldehydes and ketones also may be formed into gel compositions in accordance with embodiments of the invention.
